This morning's 15.04 updates broke two of my machines as well. After much hair-pulling I found this bug report.
Enabling 'proposed' and updating to the kernel contained therein, or switching to the -15 kernel is enough to get the driver to build. However, in both cases, attempting to enable multi-screen mode via amdcccle (with screen 1 right of screen 2) causes X to crash severely, as soon as you hit "OK" or "Apply". Both screen go into standby mode, the disk access light goes solid, and the system hard-locks (can't SysRq-REISUB). The Reset button is the only way to recover from this state, and the dual-screen mode never got saved. This is a fresh install of 15.04, with a "put all my stuff in" script, hence it's theoretically identical to what was installed initially, aside from enabling "proposed" for this attempt. This is on a machine that has run fglrx without incident from roughly 12.04 to whatever state 15.04 was in at the end of the day yesterday. The open source driver works fine in all respects, aside from being slower than fglrx on this hardware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1479913 Title: SRU request: fglrx.ko fails because of backported GPL-only 'pci_ignore_hotplug' symbol To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1479913/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
